Instructions for HD74AC670P
Power Supply:
- Ensure the supply voltage (VCC) is within the range of 2.0V to 5.5V.
- Connect VCC to the power supply and GND to ground.
Input Signals:
- Apply input voltages that comply with the specified VIH and VIL levels.
- Avoid exceeding the maximum input voltage which should not be greater than VCC.
Output Handling:
- The output voltage levels (VOH and VOL) must be considered when connecting to other devices or circuits.
- Ensure load currents do not exceed the specified limits to maintain output voltage integrity.
Propagation Delay:
- Be aware of the propagation delay time (tpd) especially in timing-sensitive applications. At 5V, it typically operates around 7ns.
Power Consumption:
- Monitor the quiescent current (ICC) which is approximately 40μA at 25°C and 5V supply.
Operating Temperature:
- Ensure the device operates within its specified temperature range to avoid damage or unreliable operation.
Storage and Handling:
- Store in a dry environment and handle with care to prevent electrostatic discharge (ESD) damage.
Mounting and PCB Design:
- Follow standard PCB design guidelines for digital ICs, ensuring proper trace widths and grounding practices.
